Subject: [E-devel] [Patch] elm_genlist multi-touch smart callbacks added I added 6 multi-touch smart callbacks in elm_genlist, please refer to below. "multi,sweep,left" - Genlist has been multi-touch swept left. "multi,sweep,right" - Genlist has been multi-touch swept right. "multi,sweep,top" - Genlist has been multi-touch swept top. "multi,sweep,bottom" - Genlist has been multi-touch swept bottom. "multi,pinch,out" - Genlist has been multi-touch pinched out. "multi,pinch,in" - Genlist has been multi-touch pinched in. I think these smart callbacks are very useful for elm_genlist multi-touch effect. If this patch have any issue, please let me know. SVN revision: 55878
